%X The finite element method is combined with the mode-matching method and the multi-mode network theory to analyze the scattering and radiation characteristics of a class of planar dielectric waveguide discontinuities. Unlike the conventional method to treat the radiation as a "source-field" problem, in the present approach, the dispersion characteristics of dielectric guidedwave structures are calculated first, and then the radiation problem is transferred to the propagation problem of a series of surface-waves and space waves from the viewpoint of scattering, thus the analysis is tremendously simplified.
